Descriptions

The Kerberos 5 (aka krb5) PAM module in Apple OS X before 10.12 does not use constant-time operations for determining username validity, which makes it easier for remote attackers to enumerate user accounts via a timing side-channel attack.

El módulo PAM de Kerberos 5 (también conocido como krb5) en Apple OS X en versiones anteriores a 10.12 no utiliza operaciones de tiempo constante para determinar la validación de nombre de usuario, lo que facilita a atacantes remotos enumerar cuentas de usuario a través de un ataque de sincronización de canal lateral.
